我收到此错误。

我正在从数据库中读取数据。以前可以对它进行排序吗？
编辑：
public void setupAndShowGraph() {
GraphViewData graphViewData[] = new GraphViewData[DatabaseSQLiteHelper.percentage.size()];
for (int index = 0; index < DatabaseSQLiteHelper.percentage.size(); index++) {
graphViewData[index] = new GraphViewData(DatabaseSQLiteHelper.date.get(index), Double.parseDouble("" + DatabaseSQLiteHelper.percentage.get(index)));
}
drugGraphSeries = new GraphViewSeries(graphViewData);
GraphView lineGraphView = new LineGraphView(getActivity(), "");
lineGraphView.getGraphViewStyle().setGridColor(getResources().getColor(R.color.golden_brown));
lineGraphView.getGraphViewStyle().setHorizontalLabelsColor(getResources().getColor(R.color.golden_brown));
lineGraphView.getGraphViewStyle().setVerticalLabelsColor(getResources().getColor(R.color.golden_brown));
lineGraphView.getGraphViewStyle().setTextSize(15.0F);
lineGraphView.setScrollable(true);
lineGraphView.setScalable(true);
((LineGraphView) lineGraphView).setDrawBackground(true);
lineGraphView.addSeries(drugGraphSeries);
LinearLayout linearLayout = (LinearLayout) rootView.findViewById(R.id.graphView);
linearLayout.addView(lineGraphView);
}
我添加了setupAndShowGraph（）方法。您可以在下面的行中看到
graphViewData[index] = new GraphViewData(DatabaseSQLiteHelper.date.get(index), Double.parseDouble("" + DatabaseSQLiteHelper.percentage.get(index)));
我使用上面的行获取数据，所有要添加的内容，以便我可以获得一个已排序的系列。
答案 0 :(得分：0)
创建一个数组来保存系列的值：
Double[] valueArray = new Double[DatabaseSQLiteHelper.percentage.size()];
填充数组：
for (int index = 0; index < DatabaseSQLiteHelper.percentage.size(); index++) {
valueArray[index] = Double.parseDouble("" + DatabaseSQLiteHelper.percentage.get(index));
}
对数组进行排序：
Arrays.sort(theValue);
最后，填写GraphViewData：
for (int index = 0; index < DatabaseSQLiteHelper.percentage.size(); index++) {
graphViewData[index] = new GraphViewData(DatabaseSQLiteHelper.date.get(index), valueArray[index]);
}
drugGraphSeries = new GraphViewSeries(graphViewData);
以下是完整代码段
public void setupAndShowGraph() {
Double[] valueArray = new Double[DatabaseSQLiteHelper.percentage.size()]; // Added line
GraphViewData graphViewData[] = new GraphViewData[DatabaseSQLiteHelper.percentage.size()];
// Fill the value array
for (int index = 0; index < DatabaseSQLiteHelper.percentage.size(); index++) {
valueArray[index] = Double.parseDouble("" + DatabaseSQLiteHelper.percentage.get(index));
}
// Sort the array
Arrays.sort(valueArray);
// fill the graphViewData with the valueArray
for (int index = 0; index < DatabaseSQLiteHelper.percentage.size(); index++) {
graphViewData[index] = new GraphViewData(DatabaseSQLiteHelper.date.get(index), valueArray[index]);
}
drugGraphSeries = new GraphViewSeries(graphViewData);
GraphView lineGraphView = new LineGraphView(getActivity(), "");
lineGraphView.getGraphViewStyle().setGridColor(getResources().getColor(R.color.golden_brown));
lineGraphView.getGraphViewStyle().setHorizontalLabelsColor(getResources().getColor(R.color.golden_brown));
lineGraphView.getGraphViewStyle().setVerticalLabelsColor(getResources().getColor(R.color.golden_brown));
lineGraphView.getGraphViewStyle().setTextSize(15.0F);
lineGraphView.setScrollable(true);
lineGraphView.setScalable(true);
((LineGraphView) lineGraphView).setDrawBackground(true);
lineGraphView.addSeries(drugGraphSeries);
LinearLayout linearLayout = (LinearLayout) rootView.findViewById(R.id.graphView);
linearLayout.addView(lineGraphView);
}
